Hi,

Is there one example to call one Powershell line from VS project (using C#), and the command line is to telnet one existing Email account to send out a message?

to telnet one existing Email account to send out a message?

Why do you want to launch Telnet to send a mail ?

Can't you use one of the numerous interfaces/classes to send a mail ?

Hi, Peter_1985

The snippet below works for me. For your reference: https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/send-mailmessage?view=powershell-7.3

            PowerShell ps = PowerShell.Create();
            ps.AddScript("$UserName = '******@XXX.com'");
            ps.AddScript("$Password = ConvertTo-SecureString passwordtoken -AsPlainText –Force");
            ps.AddScript("$cred = New-Object System.Management.Automation.PSCredential($UserName,$Password) ");
            ps.AddScript("Send-MailMessage -From '******@XXX.com' -To '******@XXX.com' -Subject 'Test mail' -SmtpServer 'smtp.XXX.com'  -Credential $cred");
            ps.Invoke();

Best regards,

Can you advise it is fine to put the following?

Can you help to

The type or namespace name 'PowerShell' could not be found (are you missing a using directive or an assembly reference?)

due to the current code?

You need to download nuget Package: System.Management.Automation and using System.Management.Automation;. PowerShell.AddScript Method

Peter_1985 2,846

I tried to run

dotnet add package System.Management.Automation

in NuGet and got issue below.

dotnet : Could not find any project in `C:\...\`.
At line:1 char:1

I can't reproduce your problem. Please try right-click the project-> Manage Nuget Packages->Browse: System.Management.Automation. The default version uses . Net7.

Yes, I installed the above one but still had issue "The type or namespace name 'PowerShell' could not be found (are you missing a using directive or an assembly reference?)"

Minxin Yu 13,506 Microsoft External Staff

Did you add using System.Management.Automation; and the project should be .NET7

using  System.Management.Automation;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
            PowerShell ps = PowerShell.Create();
            ps.AddScript("$UserName = '******@XXX.com'");
            ps.AddScript("$Password = ConvertTo-SecureString 'RealPass' -AsPlainText -Force");
            ps.AddScript("$cred = New-Object System.Management.Automation.PSCredential($UserName,$Password) ");
            ps.AddScript("Send-MailMessage -From '******@XXX.com' -To '******@XXX.com' -Subject 'Test mail' -SmtpServer 'smtp.XXX.com'  -Credential $cred -UseSsl");
            ps.Invoke();
            Console.WriteLine("Hello, World!");
        }
    }
}

Please check the installed nuget package. If your System.Management.Automation is Version 7.X, .Net7 is needed in Visual Studio Installer。

Can you share the exact steps that you can get into the following?
Minxin Yu 13,506 Reputation points Microsoft External Staff

2023-03-13T06:53:38.1966667+00:00
search visual studio installer or it could be found in Win

click individual components and search .net

Thanks a lot. .Net 7.0 is not available below.
Minxin Yu 13,506 Reputation points Microsoft External Staff

.NET6 and 7 is available in Visual Studio 2022. For vs2019 .NET framework 4.7, try nuget package Microsoft.PowerShell.5.ReferenceAssemblies

I have the codes below on the deployed project. I was using the real domain account to this. But the message was not well received. How to identify the issue of this?
                    PowerShell ps = PowerShell.Create();
                    ps.AddScript("$UserName = '******@abc.org'");
                    ps.AddScript("$Password = ConvertTo-SecureString '???' passwordtoken -AsPlainText –Force");
                    ps.AddScript("$cred = New-Object System.Management.Automation.PSCredential($UserName,$Password) ");
                    ps.AddScript("Send-MailMessage -From '******@abc.org' -To '******@gmail.com' -Subject 'Test mail' -SmtpServer 'smtp.abc.org'  -Credential $cred");
                    ps.Invoke();

ps.AddScript("$Password = ConvertTo-SecureString '???' passwordtoken -AsPlainText –Force");

Passwordtoken means your password '???'. ps.AddScript("$Password = ConvertTo-SecureString '???' -AsPlainText –Force");

I actually put the correct password to that (in the project file)
Minxin Yu 13,506 Reputation points Microsoft External Staff

2023-03-13T09:57:10.48+00:00

I mean passwordtoken is not needed if '??? 'is your real password in your snippet.

Please check the difference below:
ps.AddScript("$Password = ConvertTo-SecureString '???' -AsPlainText –Force");
ps.AddScript("$Password = ConvertTo-SecureString '???' passwordtoken -AsPlainText –Force");// in snippet , passwordtoken is duplicate
